Origin
Meaning and origin of Adamonis
The surname ADAMONIS is of Lithuanian origin and dates back to the 16th century. It is derived from the Lithuanian personal name Adam, which in turn comes from the Hebrew name Adam, meaning "earth" or "red earth." The suffix "-onis" is a common Lithuanian patronymic ending, indicating that the name originally referred to a son of Adam.
One of the earliest recorded instances of the ADAMONIS name can be found in the 1567 Lithuanian Metrica, a collection of official documents from the Grand Duchy of Lithuania. The name is mentioned in connection with a land grant in the Vilnius region.
During the 17th and 18th centuries, the ADAMONIS name was particularly prevalent in the Kaunas and Vilnius regions of what is now Lithuania. Some variations in spelling included Adamowicz and Adamovič, reflecting the influence of Polish and Belarusian languages in those areas.
A notable bearer of the ADAMONIS name was Jurgis Adamonis (1737-1803), a Lithuanian priest and author who wrote several religious works in the Lithuanian language. His book "Diewo Žodžio Šėtra" (The Tent of God's Word), published in 1781, is considered an important contribution to Lithuanian literature.
Another individual of note was Antanas Adamonis (1858-1933), a Lithuanian politician and journalist who played a significant role in the Lithuanian independence movement in the early 20th century. He served as a member of the Vilnius Conference in 1905, which advocated for greater autonomy for Lithuania within the Russian Empire.
In the 19th century, the ADAMONIS surname also appeared in records from the Grodno region of modern-day Belarus, which was part of the Russian Empire at the time. One example is Tomas Adamonis (1829-1911), a landowner and philanthropist who funded the construction of several schools in the area.
Moving into the 20th century, Viktoras Adamonis (1897-1975) was a Lithuanian artist and painter known for his landscapes and portraits. He studied at the Vilnius Art School and later became a professor at the Kaunas Art Institute.
Finally, Juozas Adamonis (1910-1983) was a Lithuanian writer and poet who was active during the Soviet period. His works often explored themes of rural life and the struggles of the Lithuanian people under Soviet rule.
While the ADAMONIS name is still found in Lithuania and among the Lithuanian diaspora, its greatest historical significance lies in its roots in the country's cultural and political history, particularly in the 16th to 20th centuries.

The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Adamonis surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
